DOOR-FASTENER.

Speccatcn of Letters Patent,

Patented Oct. 13, 1908.

Application filed Junel, 1908. Serial No. 438,560.

To all whom it may concm: V Be it known that I, MIOKUS N. STOFFELS, acitizen of the United States, residing at Medaryville,' in the county ofPulaski and State of Indiana, have invented certain new and usefulImprovements in Door-Fasteners, of which the following is aspecification, reference being had to the accompanying drawngs. v i

. My invention relates to improvements in door fasteners of the slidingbolt type and more particularly to one' designed for use upon barn doorsand the like.

The object of the invention'is to provide a simple and practical deviceof this character which may be Conveniently operated and which willeffectively fasten the door at both its top and bottom;

With the above and other objects in view, the invention consists of thenovel features of Construction and the combination and arrangem'ent ofparts hereinafter fully described and claimed, and illustrated in theaccompanying drawings, in which Figure 1 is a front elevation of aportion of a barn door illustrating the application of my inventionthereto; Fig. 2 is a vertical section taken on the plane indicated bythe line 2-2 in Fig. 1; Fig. 3 is a detal horizontal section taken onthe plane ofthe pivot 22; and Figs. 4, 5, 6 are perspective views of thesliding bolt and its two keeper plates.

In the drawings 1 denotes a portion of a wall or other structure havinga door opening 2 closed by` a door 3 which may be nounted either toswing or to slide horizontally.

My improved fastener comprises a vertically disposed sliding bolt 4arranged to eX- tend the full height of the door and mounted forvertical movement in upper and lower bearing plates 5, 6. The bolt orfastener 4 is of rectangular shape in cross section and the hearingplates 5, 6 have centrally disposed U-shaped portions to receive it andoppositely projecting apertured ears or ends to receive fastening screws7. The lower end of the bolt 4 has its inner and outer faces slightlybeveled or tapered, as shown at 8, to enter an opening 9 in a keeperplate 10 which is arranged upon the door sill and secured by screws orsimilar fastenings passed through apertures 11 formed in it.

The upper end of the bolt 4 is provided with an offset portion in theform of a substantially rectangular loop formed by bending said endoutwardly, as shown at 12, then* arranged at' the top of the dooropening 2 and e is secured to the wall or frame of the door by screws orsimilar fastenings passed through apertures 18 formed in it. The lookingtongue or projection 15 is disposed close to the outer face of the wall1 and the outer edge of the keeper plate 17 projects so that said tonguemay enter the opening 16 when the bolt 4 movesdownwardly. It will thusbe seen that when said bolt is moved downwardly its lower end 8 willenter the keeper plate 10 and its upper end or tongue 15 willosimultaneously enter the keeper plate 17,

thereby looking the door at both its bottom and top.

In order to actuate the bolt 4 I preferably form upon it', at a pointsuitably distant from its bottom, a longitudinal series of rack teeth 19which project outwardly and are adapted to engage the teeth of a segment20 formed upon one end of a hand lever 21 and ivoted by a bolt or thelike 22 between earing plates 23. The latter are angular in shape andare disposed on opposite sides of the bolt 4 so as to assist the plates5 and 6 in guiding said bolt. The short base flanges of said hearingplates are apertured to receive fastening screws 24 and their paralleloutwardly projecting fianges are of substantially circular form so as tocover and protect the teeth of the rack 19 and segment 20. It will beseen that when the lever 21 is swung upwardly the bolt will be projected downwardly to its locked position and that when said lever isswung downwardly the bolt will be lifted or retracted.

It will be understood that the invention may be used upon either sin leor double doors or gates and that it is weTl adapted for use upon thedoors of warehouses and business houses.

From the foregoing it will be seen that my invention provides anexceedingly eifective fastener for a barn door or the like, and onewhich is simple and comparatively ineXpensive in Construction and at thesame time easy and convenient to operate and strong and durable in use.

Having thus described my invention what I claim is:

1. The combination with a wall having a door opening and a door to closesaid opening, of keepers upon the Wall, a bolt slidably mounted upon thedoor and provided at one end With an ofiset loop having a locking tongueto engege one of said keepers, the other end of the bolt being adaptedto simultaneously engage the other keeper, a rack upon the intermediateportion of the bolt and a lever fulcrumed upon the door and having asegment in mesh With said rack.

2. The combination With a Well having :L door opening and a door toclose said opening, of keeper plates arranged at the top and bottom ofthe opening, guides upon the door, a vertically disposed bolt slidablymounted in said guides, the lower end of the bolt being adapted to enterthe lower keeper plate and its upper end being shaped to provide enoliset loop having a depending looking tongue to drop into the keeperplate at the top of the door opening, a series of rack teeth formed uponthe intermediate portion of the bolt, a bearing upon the door, and alever having a segment in mesh With the rack teeth and pivoted to saidbearing.

3. The conbination With a Wall having a door opening and a door for thelatter,.of upper and lower :Lpertured keeper plzttcs se- Cured in thedoor opening, upporud lower guide plates' upon the door, e vertieellydisposed bolt slidably .nounted in seid guide plates, the lower end ofthe bolt being &depted to enter the lower keeper plete and the upper endof the bolt being bent outwzn'dly, then upwardly, then inwardly, andthen. doWnWardly to provide a depending looking tongue to drop into theuppc' keeper pinte, rack teeth forned upon the outer face of the boltintermediate its ends, &ngulur hearing plates Secured to the door onopposite sidvs of the bolt and edepted to guide the seine, :1. leverforned at one end With :L gear segment to engage seid reck teeth andpivoted hetWeen the outwardly projeeting ihngos ol' the bearing plates,seid outwardlv projecting fianges being enlzn'ged to protect the teethol' the segment and rack, substnntinlly es (lescribed.
